-180˚

#### Explanation:

There is a simple rule that can be used when converting from a measure in radians to an equivalent measure in degrees.

The rule is:

$\text{radians"xx(180˚)/pi="degrees}$

So to convert the given radian measure:

"degree measure"=-pixx(180˚)/pi

The $\pi$ in the numerator will cancel with the $\pi$ in the denominator. The minus sign will stick around leaving:

-180˚
